SOURCE: Guages or HVAC Controls don't light up
Good Day,
Sounds to me like your headlight switch needs to be replaced. When you turn your light's on (parking or headlights) the switch sends two outputs, one to the exterior lights and the other output is your cluster and hvac illuminaton. You can get a new switch from a dealer for around 30 bucks new. Here's a pic of what you need:
You do need to remove your outer dash panel to gain access.
Sorry this posting is so short, just worked a 14hr day. If you need further help with replacing the switch I can walk you though the process.
Hope this helps for now.

Not roadmaster but should be quite similar, if not same. (schematics) just in case this helps.

SOURCE: the dash lights on my 1995 nissan pickup went out
the bulbs are either blown or there is a loose wire in the back of the dash cluster if you cant find any loos wires them teh dimmer switch or head light switch may be the problem

The HVAC control, if it is the Electronic version, you might want to try unplugging, and plugging it back in. Remove the center trim panel by opening the ash tray, and pulling on each corner. The trim panel is held on with 6 spring clips ( 3 on each side ).
When you have the panel loose ( don't move too far, the HVAC controls and the Passenger Airbga Deactivated light are still hooked up ), un hook the 2 cam over connectors ( circled in blue ). After hooking back up, the HVAC will be off, you need to manually turn it on.
2. The dash lights could be the wrong bulb, or some could be blown out. F150online.com -> Technical Articles section has a thread on removing the dash to change the bulbs.
These are the 2 starting points.
